Top Ranked Companies


The Good

  • KOTA Solar Panels
  • KOTA Backup Battery
  • KOTA Financing Options
  • KOTA Solar Warranty and Quality Inspection
  • Solar Service Area

KOTA Solar Panels

KOTA solar panels are supplied by REC, a company that makes solar panels with higher outputs, higher quality, and better aesthetics for both residential and business properties.

REC supplies solar panels to many solar installation companies across the country and offers a variety of solar panels, including the award-winning REC Alpha Series.

Featuring a sleek design with no visible circuitry while producing 20 percent more energy per square meter than traditional solar panels, the REC Alpha Series is a standout in the industry.

KOTA Backup Battery

Backup battery systems charge with the energy produced by your solar panel system and give you access to power in the case of a power outage. Ensuring that you have a reliable backup battery in addition to solar panels ensures that you can keep your home essentials running at any time. 

KOTA supplies and installs LG Pro backup batteries, a popular battery choice in the industry due to their efficient energy storage. Over time, battery performance may decline, which is common and not unique to LG backup batteries.

For that reason, it is important to monitor battery performance and conduct regular maintenance — KOTA attends to all product maintenance and will be your point of contact for any maintenance needs.

KOTA Financing Options

KOTA makes going solar more attainable by offering solar financing solutions. The company knows that even with tax incentives, solar panels and installation is a large investment, but one that shouldn’t keep you from making the switch to solar energy. KOTA offers the following financing options:

  • Loan — A loan provides you with the benefits of solar with no upfront costs. This option is ideal for those who prefer financial flexibility and don’t want to tie up their cash upfront.
  • Cash/Buy — This option requires upfront payment for your solar system at the time of installation. If you don’t want to be responsible for solar and interest payments, and you have the cash on hand, this could be a good option for you.
  • PPA (Power Purchase Agreement) — With a PPA you pay for the energy your system produces at a lower rate than your utility provider. Instead, the solar company owns the system and your yearly rate is locked in at a specific rate (typically not exceeding 2.9%).

It is important to speak with a KOTA representative to assess which financing option will be the best fit for your needs.

KOTA Solar Warranty and Quality Inspection

KOTA offers a 25-year workmanship and roof penetration warranty. Additionally, KOTA Energy Group conducts an 86-point quality inspection prior to turning your solar system, ensuring that everything is functioning properly and efficiently. 

Warranties are standard within the solar industry. Typically, manufacturers will offer an equipment warranty on their products. This warranty ranges anywhere from 15 to 25 years, which is the anticipated lifespan on solar panels.

Then solar companies that actually install solar systems will provide a workmanship warranty to protect clients from any errors in the installation process. The industry standard workmanship warranty is 10 years.

Solar Service Area

Many solar companies only offer solar installation services in one state or even just the most populated cities within a particular state. However, KOTA Energy Group has a wide reach and services thirteen states.

KOTA Energy Group services the following states:

  • Arizona
  • California
  • Colorado
  • Florida
  • Illinois
  • Massachusetts
  • New Jersey
  • New York
  • Nevada
  • North Carolina
  • South Carolina
  • Texas
  • Utah

It is worth noting that since its founding in 2018, the KOTA service area has grown, indicating that the company could continue expanding its reach.


The Bad

  • KOTA Solar Pricing Transparency
  • Unclear Company Branding

KOTA Solar Pricing Transparency

KOTA doesn’t provide any pricing details on its website which can make it difficult to make quick comparisons or estimates on what you can expect to pay for KOTA solar panels and installations.

Solar panels typically cost $16,000 on average, but costs can vary widely based on the type of panels, type of inverters, system balancing, etc.

You can get a free quote on the KOTA website or you can call and speak with a company representative to talk about your solar needs and budget restrictions.

Unclear Company Branding

Currently, KOTA has two websites: KOTASolar.com and KOTAEnergyGroup.com. Both websites feature the same content and information, but it can be confusing because it appears that the company may have two separate services even though it only offers solar installation services.


The Bottom Line

KOTA Energy Group provides solar installation services in thirteen states across the country. The company installs REC solar panels and also provides LG Pro backup battery installation, products which are both high quality and popular in the industry.

Solar panel installation is an investment and can be an expensive process. For this reason, KOTA offers financing options, such as a loan or a PPA. A KOTA representative will work with you to determine the best financing option for your needs. To protect your solar investment, the company also provides a competitive 25-year workmanship and roof penetration warranty.

Bill Dam

I had my solar system installed by KOTA recently. They checked off every single box: sales rep, installers and installation quality, price, responsiveness, warranties, product and equipment, customer service.. 10/10 for everything!!! I am very happy with everything from beginning to end. The sales rep, Lauren B, came to my door about a month ago. At first, I was very skeptical because my bill was pretty low. Lauren was able to show me the value of solar and still manage to bring my monthly payments to a price that is less than what I pay for electricity today, and I am getting 2x as much power as I use today, AND they installed a charger for my Tesla that arrived this week. Lauren explained every step of the process to me. She made it to where I didn't even have to lift a finger! Her knowledge of solar and everything she did to understand my needs and make sure my system was tailored exactly to the needs of my house gave me confidence every step of the way. She never came to my house empty handed, always had thoughtful and meaningful gifts with her. The price was also EXCELLENT. It was the best price of all bids I got. I have been impressed with Kota every step of the way. The technicians and installers were also a pleasure to work with. They did my whole installation in half a day and were very hardworking men. I would HIGHLY recommend KOTA Solar and the sales rep Lauren B to anyone considering solar for their home.

Wonderful customer service getting solar with KOTA! I was a little curious about solar but assumed it was too expensive. However, when our friendly representative from KOTA (Jake R) visited our door and mentioned that the federal solar tax credit was extended, I decided to sit down and learn more. I am glad I did! Jake explained the process, benefits, and financial breakdown very well and answered all my questions. He was also patient when I asked him to come back in a few days, so I had time to get other quotes. After doing more research and looking at competitors, I decided to move forward with KOTA. Throughout the whole process, Jake kept us up to date and answered questions, stopped by for all the key steps, and was courteous and professional. The whole process was surprisingly quick, and it now feels great to be generating solar energy for less cost than I was paying the utility company. We highly recommend KOTA Energy for your home solar. I can’t imagine a better customer service experience, and the product and installation are top-notch.

Some great news for my rooftop and all thanks to Kristian T. and KOTA! He dropped by to see if he could help me save money and energy. His kind and professional approach was very much appreciated. He provided supportive knowledge regarding solar. I had done much research on the benefits of solar so I was pleasantly surprised to find his presentation accurate and well designed for my needs. He took all the time I wanted for full comprehension of the products he had to offer and to explain the procedure for installation. Kristian's kindness and care were the primary aspects of the follow up that made it easy for me to refer my family and neighbors. I knew the solar products were the highest quality and the person offering them matched the product. I actively referred others because of the quality of the entire experience. My energy bills reflect the financial gain solar has been for me. The pleasant experience and high-quality products are fantastic additions to the energy savings I have documented since the solar panel installation. Kristian stopping by to offer his products and exceptional customer service has proven to be a total game-changer for me in so many ways.

Definitely like the way these guys show up! The first guy came to my door the other day and I was on a call then he came back again today after me telling him to “beat it!” I can appreciate someone who doesn’t take no for an answer and I like that it didn’t even phase the guy! As for the equipment I can’t say just yet but my neighbor seemed to have a good Experience with them so I’m going to at least hear the guy out. I will update after our next interaction!

I have given Kota Energy Group a lot of time to make things right with the recent lack of professional service I have received from them. I want to share my experience with anyone that maybe considering business with KOTA. I have emails, text messages, call logs, and USPS certified letter receipts to validate the below mentioned. I believe that it is important to share my experience. I will start off by saying all the field technicians and installers that came out to my house were very professional and courteous. Now, to briefly explain the horrible experiences with this company. For starters I was in the solar process for six (6) months. The experience included errors on paperwork submitted to “Southern California Edison” (SCE), three (3) “no-call, no-shows,” lies told by project managers, several calls and text messages to project managers left unanswered/not replied too, over 60-80 broken tiles on my roof were (replaced after I reached out), and a drive down to the Newbury Park office only to be told there was no one there for me to speak with. I conducted A LOT of follow-ups between Edison and KOTA on my end to get the project completed, including getting my “permission to operate (PTO)” pushed through. On Kota’s website they state “HOW WE DO IT, we care from your initial contact with KOTA, all the way through installation and system activation, we are hyper focused on making sure you know we care. You’ll see it in the details of our everyday operations. We care about your experience going solar, and we care about our planet.” This is not upheld at all by the administration of KOTA. I have sent approximately 4-5 rounds of emails to management teams at KOTA and have not received any responses. I have sent three (3) rounds of USPS certified letters to project managers and executives which include the CEO of the company and have received ZERO responses. I was told by two (2) project managers that the CEO would call me, but I am still waiting for that call today. All the correspondence was regarding my poor customer experience with KOTA. Again, I am sharing my six months of adventures so that if you are considering this company, you won’t have to experience the level of incompetence for a service that you are paying a lot of money for. SPEND YOUR MONEY WITH A WORTHY COMPANY.

Thomas Triggs Ventura, CA

Kota installed solar panels right next to an old hot water heater vent that prevents 2 of our panels from performing at full capacity. At first Kota refused to address the issue and basically said the pipe is the problem. That is exactly my point. They are the experts so why would they propose putting the panels so close to the vent in the first place. After dozens of attempts to get them to address the issue they finally scheduled a day to come out and look at the issue. An hour before the appointment they texted a cancellation message saying they’d get back with me with a new day. They didn’t do so. After another call they had me on hold once again. They then proposed charging me to remove the panels while I paid another company to remove the vent and then Kota would charge me to reinstall the panels. It has been maddening trying to deal with this company after they received payment for the panels and installation. I expect them to take responsibility for their error and make this right in order for us to get 100% out of our panels. We specifically went through all of our future electrical needs when deciding on the number of panels to install and now we are not getting what we paid for. We are extremely disappointed and expect this matter to be rectified.

This company sends their employees out to give an estimate and make you feel as though they can give you exactly what you want when the company actually cannot do all the salesman said they could! Since they had to upgrade our panel for the solar and asked them if they could upgrade our panel with more breakers! Raymond, their salesman, "Sure, no problem! We can do that for you!" We needed a roof as well, roofers were efficient and did a great job! Solar installers were quick and they did their job but the electrical people did not install what we thought we had purchased! All this time (btw, we initially began this whole process in May 2021, it is November 6, 2021 and our solar has not been turned on yet!) Raymond lead us onto believing that we had purchased additional breakers! Well after their installation of the panel, we go outside and the panel has exactly the same amount of breakers that we already had, no added breakers were added like we had been discussing several times with Raymond! We immediately called Raymond, the salesman, to tell him that our panel was not upgraded with extra breakers! He said he was calling his bosses to find out why it wasn't upgraded! I called several times and each time he kept saying they (the bosses) weren't getting back to him! It wasn't until I wrote a review about this company's shady practices that they immediately responded! Now they said Raymond says he never told us they could upgrade our panel! Hahaha, that's funny that I have a text message from Raymond asking if they were able to upgrade our panel? Beware of this companies lying promises and unethical sales tactics just to make a sale!! Our contract also says we bought 30 panels, there are only 28 panels up on our roof! I received a phone call from the CEO, he wants to clarify and find out exactly what Raymond told they could do for regarding the upgraded breakers so the CEO sets a date and time for this 3-way conversation to happen on. I still had to call him because he (the CEO) never responded and the agreed upon 3-way phone day! This alone speaks volumes about their company's poor communication when the CEO sets a date and he can't keep it! So when the 3-way phone conversation does finally happen between myself, the CEO and Raymond, Raymond then says he never told us this! I told him he was lying and the owner then says, "I got hit in the head with a golf ball and I have a headache and I have to hang up!" These is how the CEO handles business! There is nothing worse than a lier, this says a lot about the integrity and character of the employees and company and owner! Just Beware! No wonder they are not one of the top 5 solar companies, no integrity! Do your solar homework and choose wisely!

The worst Solar company. We have unobstructed roof and one of the panels is underproducing a lot. VP of the company said yes it is and it would cost too much to replace(yes $50,000 and a warranty) the one panel it would make them not make as much money on the deal. WHAT? Bad product and they won’t honor their warranty. The whole system is only two years old. Beware of this company. Untrustworthy and downright dishonest.
